[0002]

2. Description of the Related Art Conventionally, various types of fire detectors have been proposed, but the fire detector is usually provided with a confirmation light for displaying the operation status when the alarm is issued.

This confirmation light is not only for confirming which fire detector is issuing a warning when the fire detector gives a warning, but also for operation tests such as a smoke test and a heating test. In this case, it is also used to confirm whether the fire detector operates normally.

FIG. 12, 13 or 14 is a view schematically showing an example of a conventional fire detector with a confirmation light.

A fire detector G shown in FIG. 12 has a headlamp 103 integrally formed with a confirmation lamp 101 including a light emitting element such as an LED, a base portion 102 mounted on a ceiling or the like, and a recess 103a in the center. And a fire detection unit 104 provided in the central portion of the head body 103 and accommodating a sensor (not shown) such as a smoke sensor and / or a temperature sensor, and a confirmation lamp accommodated in the recess 103a of the head body 103. 101 and a circuit board 105 provided with an electric circuit device (not shown) for operating a sensor (not shown). Then, the lower top surface S10 in the vicinity of the fire detection unit 104 of the head body 103.
A hole 103c is provided in 3a, and the confirmation lamp 10
1 is mounted in the hole 103c.

Further, in the fire detector H shown in FIG. 13, compared with the fire detector G, the lower surface S of the head body 103 is lower.
A hole 103c is provided on the outer peripheral side of 103a, and the light emitting element used as the confirmation lamp 101 has a hole 1c.
It is installed in 03c. In the fire detector H, the head body 103 has an upper head body portion 103x and a lower head body portion 103, as shown in the figure.
It has a so-called two-piece structure of y. And
In this fire detector H, the confirmation lamp 101 is connected to the fire detector G.
Compared to the above, the lower top surface S103a of the head body 103
Since a large circuit board must be used as the circuit board 105a provided with the electric circuit device (not shown) because it is provided on the outer peripheral side of the head body 103, the circuit board 105a is not provided in the recess 103a of the head body 103. Accommodated in the head body 103.

Further, in the fire detector J shown in FIG. 14, a light emitting element is used as the confirmation lamp 101, and the base portion 10
2 is provided with a projecting portion 107 having a hole portion 107c on the outer peripheral side surface S102b.
It is installed in 7c. In this fire detector J,
A confirmation lamp 101 and an electric circuit device (not shown) for operating the confirmation lamp 101 are provided separately from a circuit board 105b provided with an electric circuit device (not shown) for operating a sensor (not shown). The circuit board 110 is provided with.

Further, in the conventional fire detectors G, H and J,
In each case, the light-emitting element such as the LED used as the confirmation light 101 has the circuit boards 105, 105a,

At the same time as mounting on the base portion 102, the fire detector and the fire alarm are electrically connected.

[0010]

By the way, a fire detector G as shown in FIG.
Since an integrally molded product is used and a small circuit board 105 that can be accommodated in the recess 103a of the head body 103 is used, there is an advantage that the manufacturing cost of the fire detector G can be kept low. However, since the confirmation light 101 is provided on the circuit board 105, the confirmation light 1
The position 01 is extremely close to the fire detection unit 104. Therefore, when performing an operation test such as a smoke test or a heating test to determine whether or not the fire detector G normally operates, a cylindrical tubular body 10a as shown by an imaginary line in FIG.
When the fog tester 10 having the above is installed under the fire detector G, the confirmation lamp 101 causes the tubular body 10 of the fog tester 10.
There was a problem that the tester of the fire detector G could not see the confirmation light 101 because it entered the inside of a.

In such a case, the tester or the like is required to use the fog tester 1
Since the confirmation lamp 101 of the fire detector G is normally turned on by inclining 0, the problem that the operation test is troublesome, and tilting the fog tester 10 There was a problem that the accuracy of the test deteriorated.

On the other hand, a fire detector H as shown in FIG.
Since the confirmation light 101 is provided on the outer peripheral side of the head body 103, even if the fog tester 10 is installed below the fire sensor H, the confirmation light 101 still causes the fog tester 10 to have a cylindrical body 10a. Since it is located on the outer side, although there is an advantage that a tester or the like can easily confirm whether or not the confirmation lamp 101 is normally turned on during the operation test without tilting the fog tester 10, Since a large-sized board must be used as the circuit board 105a, the manufacturing cost of the circuit board 105a provided with an electric circuit device (not shown) is high, and the circuit board 105a is large. Since the circuit board 105a must be housed in the head body 103 having a two-piece structure as shown in FIG. 13, the structure of the fire detector H is complicated and the manufacturing cost is low. There is a problem that Kunar.

Further, a fire detector J as shown in FIG.
Since the confirmation light 101 is provided in the protruding portion 107 provided by protruding on the outer peripheral side surface of the base portion 102, even if the fog tester 10 is installed under the fire detector J, the confirmation light 101 is confirmed. Since the lamp 101 is located outside the tubular body 10a of the fog tester 10, the tester can easily confirm whether or not the confirmation lamp 101 of the fire detector J is normally turned on during the operation test. Although there is an advantage, it is necessary to provide the confirmation lamp 101 and the circuit board 110 for operating the confirmation lamp 101 separately from the circuit board 105b provided with the electric circuit device (not shown) for operating the sensor. There is a problem that the structure of G becomes complicated and the manufacturing cost becomes high.

Further, in the conventional fire detectors G, H and J,
In each case, since the light emitting element used as the confirmation light 101 is attached to the lower surfaces S105b, S105ab, S110b of the circuit boards 105, 105a, 110 downwardly and substantially vertically as shown in the figure, the design of the fire detector can be improved. The degree of freedom is limited, and the fire detector cannot be thinned, which also causes a high manufacturing cost.

Furthermore, in the conventional fire detectors G, H, and J, when the head body 103 is attached to the base portion 102, the blade blades 121 and 121 of the base portion 102 are attached to the blade blades of the head body 103 (not shown). If the fire detectors G, H, and J are normal, even if (No.) is not completely fitted, the operation of the operation test will turn on the confirmation lamp 101. Therefore, the fire detectors G, H, and J are attached. There is a problem that a builder or the like cannot confirm whether or not the blades (not shown) of the head body 103 are completely fitted to the blades 121, 121 of the base portion 102.

The present invention has been made in order to solve the above-mentioned problems, and an electric circuit device (not shown) for operating a sensor or the like is a small-sized single piece that can be housed in a fire detection part. When using a board and performing an operation test, it is easy for the tester to visually check whether or not the confirmation lamp is lit, and to check whether the head body is completely attached to the base. It is an object of the present invention to provide a fire detector with a confirmation light, which has a simple structure and can be manufactured at low cost.
